PopCast

For mac there's an application called beamer (https://beamer-app.com/) that's already out and the same price

Finally something simple for casting to various devices!

Expensive when you can use other alternatives like Video Stream for Chromecast (http://www.producthunt.com/tech/...). You can also use AirParrot (http://www.producthunt.com/tech/...) which is also $15 but has so many other features included like screen mirroring.
